It would be very useful when clicking into details of a show, to list countries it is available in. It appears that you have all the data, just a matter of displaying it. The reason this is useful is when recommending movies to friends, or when traveling, I could at a quick glance know what country a particular show is available in, and on what service. Contrast this to the current search, where you have to change countries back and forth to see availability.

I think it would be great if you could actually have section when you
can find movies that are only streaming in one page. For example, I only
have Netflix so it would be nice to only see what movies are streaming
online in Netflix (the same with itunes, hulu, etc., por other people).
